Methods, systems, and computer readable media may be operable to facilitate an anticipation of an execution of a process termination tool. An allocation stall counter may be queried at a certain frequency, and from the query of the allocation stall counter, a number of allocation stall counter increments occurring over a certain duration of time may be determined. If the number of allocation stall counter increments is greater than a threshold, a determination may be made that system memory is running low and that an execution of a process termination tool is imminent. In response to the determination that system memory is running low, a flag indicating that system memory is running low may be set, and one or more programs, in response to reading the flag, may free memory that is not necessary or required for execution.

IDO plays a major role in immune regulation, and its immunosuppressive function manifests in several manners. A pathophysiological link exists between IDO and cancer. Disruption of immune homeostasis is intimately involved with tumor growth and progression, and the production of IDO in the tumor microenvironment appears to aid in tumor growth and metastasis. Moreover, increased levels of IDO activity are associated with a variety of different tumors (Brandacher, G. et al., 12(4):1144-1151 (Feb. 15, 2006)). In addition to cancer, IDO has been implicated in, among other conditions, immunosuppression, chronic infections, and autoimmune diseases or disorders (e.g., rheumatoid arthritis).Substituted quinolinylcyclohexylpropanamide pharmaceutical compounds that inhibit IDO and are useful for the treatment of cancer have been previously described. See, e.g., WO2016/073770. Improved methods of making such compounds, which reduce production costs and improve production safety, are, therefore, needed.The disclosure is directed to methods of making compounds of formula I, or stereoisomers thereof:contacting the compound of formula III, or a stereoisomer thereof, with a suitable organic acid, in a suitable aqueous solvent, for a time and at a temperature sufficient for hydrolysis and decarboxylation and to ...
